At each site visit, a series of tests, measurements, and collections were conducted using the Georgia Adopt-A-Stream format and set criteria.
First, the air temperature was measured using a standard thermometer. While that was being measured, the relative humidity was measured with the device shown below. One thermometer has cloth on the bulb for a wet reading, and the other thermometer is exposed for a dry reading. The two measurements were then registered and used to define the relative humidity.
The pH was tested by mixing a small amount of stream water with ten drops of the pH wide range indicator in a 5 mL test tube. Then the water in the test tube was compared to the color scale indicator to assess the pH level. Next, the water temperature was determined by placing the thermometer in a shady spot in the stream while the additional field work continued. Dissolved oxygen was measured in parts per million (ppm), using a very carefully collected sample of water and combination of chemical drops. Conductivity was measured in uS/cm using a device that is placed in the stream for a short time. Water samples were collected and placed in ice for coliform testing later in the lab. On 26 June 2012, there was no water to sample, due to Site 1 being the headwater and consisting mainly of runoff.
